With this input dynamic range the input offset contribution to total error is negligible compared to the percent of reading error. Thus, it is specified indirectly as a part of the percent of reading error. 2 The most accurate representation of total error with low level inputs is the summation of a percent of reading term, an output offset and an input offset multiplied by the incremental gain (VY + VZ) VX. 3 When using supplies below ±13 V, the 10 V reference pin must be connected to the 2 V pin in order for the AD538 to operate correctly.
